Common NameL-Dihydroorotic acid
DescriptionL-Dihydroorotic acid, also known as (S)-4,5-dihydroorotate or dihydro-L-orotate, belongs to the class of organic compounds known as alpha amino acids and derivatives. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof. 4,5-Dihydroorotic acid is a derivative of orotic acid which serves as an intermediate in pyrimidine biosynthesis. L-Dihydroorotic acid is a drug. L-Dihydroorotic acid exists in all living species, ranging from bacteria to humans. Within humans, L-dihydroorotic acid participates in a number of enzymatic reactions. In particular, L-dihydroorotic acid can be biosynthesized from ureidosuccinic acid; which is catalyzed by the enzyme cad protein. In addition, L-dihydroorotic acid and quinone can be converted into orotic acid through the action of the enzyme dihydroorotate dehydrogenase (quinone), mitochondrial. In humans, L-dihydroorotic acid is involved in the metabolic disorder called the beta-ureidopropionase deficiency pathway. Outside of the human body, L-dihydroorotic acid has been detected, but not quantified in several different foods, such as black chokeberries, vanilla, sweet basils, soy beans, and broad beans.
